Shout about following a passage (5)
I believe the answer is:
alley
'passage' is the definition.
(thesaurus)
'shout about following a' is the wordplay.
'shout' becomes 'yell' ('yell' can be a synonym of 'shout'**).
'about' shows that the letters should be reversed in order.
'following' is a charade indicator (letters next to each other).
'yell' back-to-front is 'lley'.
'lley' after 'a' is 'ALLEY'.
(Other definitions for alley that I've seen before include "Back lane" , "Bowling lane" , "Walk" , "Narrow passage" , "Marble" .)
